Methods

#attributes

def attributes() -> ::Google::Protobuf::Map{::String => ::String}
Returns
  • (::Google::Protobuf::Map{::String => ::String}) — Optional. Attributes for this message. If this field is empty, the message must contain non-empty data. This can be used to filter messages on the subscription.

#attributes=

def attributes=(value) -> ::Google::Protobuf::Map{::String => ::String}
Parameter
  • value (::Google::Protobuf::Map{::String => ::String}) — Optional. Attributes for this message. If this field is empty, the message must contain non-empty data. This can be used to filter messages on the subscription.
Returns
  • (::Google::Protobuf::Map{::String => ::String}) — Optional. Attributes for this message. If this field is empty, the message must contain non-empty data. This can be used to filter messages on the subscription.

#data

def data() -> ::String
Returns
  • (::String) — Optional. The message data field. If this field is empty, the message must contain at least one attribute.

#data=

def data=(value) -> ::String
Parameter
  • value (::String) — Optional. The message data field. If this field is empty, the message must contain at least one attribute.
Returns
  • (::String) — Optional. The message data field. If this field is empty, the message must contain at least one attribute.

#message_id

def message_id() -> ::String
Returns
  • (::String) — ID of this message, assigned by the server when the message is published. Guaranteed to be unique within the topic. This value may be read by a subscriber that receives a PubsubMessage via a Pull call or a push delivery. It must not be populated by the publisher in a Publish call.

#message_id=

def message_id=(value) -> ::String
Parameter
  • value (::String) — ID of this message, assigned by the server when the message is published. Guaranteed to be unique within the topic. This value may be read by a subscriber that receives a PubsubMessage via a Pull call or a push delivery. It must not be populated by the publisher in a Publish call.
Returns
  • (::String) — ID of this message, assigned by the server when the message is published. Guaranteed to be unique within the topic. This value may be read by a subscriber that receives a PubsubMessage via a Pull call or a push delivery. It must not be populated by the publisher in a Publish call.

#ordering_key

def ordering_key() -> ::String
Returns
  • (::String) — Optional. If non-empty, identifies related messages for which publish order should be respected. If a Subscription has enable_message_ordering set to true, messages published with the same non-empty ordering_key value will be delivered to subscribers in the order in which they are received by the Pub/Sub system. All PubsubMessages published in a given PublishRequest must specify the same ordering_key value. For more information, see ordering messages.

#ordering_key=

def ordering_key=(value) -> ::String
Parameter
  • value (::String) — Optional. If non-empty, identifies related messages for which publish order should be respected. If a Subscription has enable_message_ordering set to true, messages published with the same non-empty ordering_key value will be delivered to subscribers in the order in which they are received by the Pub/Sub system. All PubsubMessages published in a given PublishRequest must specify the same ordering_key value. For more information, see ordering messages.

#publish_time

def publish_time() -> ::Google::Protobuf::Timestamp
Returns
  • (::Google::Protobuf::Timestamp) — The time at which the message was published, populated by the server when it receives the Publish call. It must not be populated by the publisher in a Publish call.

#publish_time=

def publish_time=(value) -> ::Google::Protobuf::Timestamp
